List	Version	Source flow	Name there	Why this flow
EF	3.1	08a91e70-3ddc-11dd-9227-0050c2490048	benzo[a]pyrene	The consensus list is built from this one, so this row is the flow itself rather than something matched to it.
bafu	2026-v1	97470bf4-f76c-5fbf-aa16-766334325ba2	Benzo(a)pyrene	The CAS numbers are the same (50-32-8); both name the same compartment.
ecoinvent	3.12	d02904aa-dc1a-43f2-86ce-b41aa9cab47c	Benzo(a)pyrene	A curator's mapping table (ecoinvent-3.11-biosphere-EF-3.1-biosphere) names this flow.
ecoinvent	3.8	d02904aa-dc1a-43f2-86ce-b41aa9cab47c	Benzo(a)pyrene	A curator's mapping table (ecoinvent-3.8-biosphere-EF-3.1-biosphere.json) names this flow.
